First EarthCARE CPR Observations of Dynamics–Microphysics Coupling in Marine Cold‐Air Outbreak Clouds

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Marine cold‐air outbreak (MCAO) clouds begin as shallow cloud streets near the ice edge and evolve into broken open‐cell convection downstream. Their rapid transitions in cloud structure and microphysics are closely linked to vertical motions, but this interplay has not previously been observed from space. The EarthCARE satellite, carrying the

The Transition from Aerosol- to Updraft-Limited Susceptibility Regime in Large-Eddy Simulations with Bulk Microphysics

Tellus: Series B, Chemical and Physical Meteorology
Large-eddy simulation (LES) is often used as a benchmark simulation in climate science and is suggested as a fundamental tool to examine, e.g., marine cloud brightening.

The remarkable inefficiency of stratocumulus

Abstract. Marine stratocumulus clouds play a central role in Earth’s climate system by reflecting incoming solar radiation and exerting a strong cooling effect. Their organization into open and closed mesoscale cellular morphologies can be thought of as an example of bistable dynamics driven by aerosol–cloud interactions and mesoscale processes.

Entrainment in stratocumulus‐topped mixed layers

Quarterly Journal of the Royal Meteorological Society, 2002
AbstractMixed‐layer theory is used to synthesize and evaluate recently proposed entrainment parametrizations (rules) for the stratocumulus‐topped boundary layer. The results illustrate that recently proposed entrainment rules exhibit marked differences.

Characterization of HRRR-simulated rotor layer wind speeds and clouds along the coast of California [PDF]

Wind Energy Science
Stratocumulus clouds, with their low cloud base and top, affect the atmospheric boundary layer wind and turbulence profile, thereby modulating wind energy resources.

Large‐eddy simulation of subtropical cloud‐topped boundary layers: 2. Cloud response to climate change

Journal of Advances in Modeling Earth Systems, 2017
How subtropical marine boundary layer (MBL) clouds respond to warming is investigated using large‐eddy simulations (LES) of a wide range of warmer climates, with CO2 concentrations elevated by factors 2–16. In LES coupled to a slab ocean with interactive

A New TKE‐Based Parameterization of Atmospheric Turbulence in the Canadian Global and Regional Climate Models

Journal of Advances in Modeling Earth Systems, 2019
A new semi‐empirical turbulence parameterization is presented. Key features of the scheme include representation of turbulent diffusivities in terms of the turbulent kinetic energy that is determined by solving a quasi‐equilibrium form of the equation ...

Slow Manifolds and Multiple Equilibria in Stratocumulus-Capped Boundary Layers

Journal of Advances in Modeling Earth Systems, 2010
In marine stratocumulus-capped boundary layers under strong inversions, the timescale for thermodynamic adjustment is roughly a day, much shorter than the multiday timescale for inversion height adjustment. Slow-manifold analysis is introduced to exploit

The Response of Cloud Dynamic Structure and Microphysical Processes to Glaciogenic Seeding: A Numerical Study

Atmosphere
Stratocumulus clouds are cloud systems composed of stratiform clouds with embedded convective clouds, possessing strong catalytic potential and serving as key target cloud systems for weather modification operations.
